When compiling and installing sphinx, a lot of Chinesegarbled characters appeared, and finally an error was thrown and got stuck. I went to the official website and directly downloaded an rpm package, and the installation was a breeze. . . I don’t want to study the specific errors. Busy with development~~
Install both packages. One is mmseg This is a program that generates Chinese dictionary The other is csft which is the Chinese version of sphinx
rpm -ivh after installation. It went very smoothly~it was installed in less than half a minute. . .
Being lazy, I went directly to csft to download the Chinese dictionary library. Very good, very thoughtful. . .
unigram.txt uni.lib
unigram.txt Dictionary text, you can add your own keywords
Then use
mmseg -u unigram.txt Generate dictionary file : unigram.txt.uni Then rename uni.lib This is the dictionary recognized by sphinx.
Where to put it? Put it in the dictionary path you configured in sphinx.conf. We will talk about it later
Then it’s almost done
Let’s take a look at some useful programs in sphinx
[root@beihai365 /]# csft-
csft-indexer csft-search csft-searchd
csft-indexer is a program that generates full-text search indexes
csft-search is used to test whether the search is effective, and it is also very easy to use. Why not use this to check whether the full-text search is successful before I have developed a client script?
csft-searchd This is the daemon for sphinx search. After starting, you can use the script php python, etc. to open query.
It’s that simple~~
Let’s take a look at the two key parts
sphinx.conf configuration file

index tmsgsindex

}

{

max_children = 30
pid_file = /var/log/searchd.pid
max_matches = 1000
#seamless_rotate = 1
#preopen_indexes = 0
#unlink_old = 1
}
source tmsgs
{
type = mysql
sql_host = localhost
sql_user = root
sql_pass = 1
sql_db = phpwind75sp3
sql_port = 3306 # optional, default is 3306
#sql_sock = /tmp/mysql3307.sock
sql_query_pre = SET NAMES gbk
sql_query = SELECT id,name,type,stock FROM pw_tools
#sql_attr_uint = id
sql_attr_uint = stock
}
index tmsgsindex
{
source = tmsgs

#min_prefix_len = 0
#min_infix_len = 2

}

}
searchd
{
#listen = 3312
log = /var/log/searchd.log
query_log = /var/log/query.log
read_timeout = 5
max_children = 30
pid_file = /var/log/searchd.pid
max_matches = 1000
#seamless_rotate = 1
#preopen_indexes = 0
#unlink_old = 1
}
再看一下 测试客户端代码
view plaincopy to clipboardprint?
header("Content-type:text/html;charset=utf-8");
include 'sphinxapi.php';
$cl = new SphinxClient();
$cl->SetServer('localhost',3312);
$cl->SetMatchMode(SPH_MATCH_ALL);
$cl->SetArrayResult(true);
$res = $cl->Query("名卡","*");
print_r($res);
?>
header("Content-type:text/html;charset=utf-8");
include 'sphinxapi.php';
$cl = new SphinxClient();
$cl->SetServer('localhost',3312);
$cl->SetMatchMode(SPH_MATCH_ALL);
$cl->SetArrayResult(true);
$res = $cl->Query("名卡","*");
print_r($res);
?>
“名卡”这个关键字是我自己手动在字典里面添加的。看是否能真的搜到
view plaincopy to clipboardprint?

完全没问题。搜索出来了。
几个关键的操作
[root@beihai365 /]# csft-searchd --stop 停止搜索守护
[root@beihai365 /]# csft-indexer --all 针对所有节点生成索引。你也可以针对某个节点生成索引比如：csft-indexer xx
[root@beihai365 /]# csft-search App 搜索关键字 App 。 不过看下面信息没有搜到和没有命中任何的文档。

当大家在运行这些命令的时候发现，需要你自己手动的置顶 --config sphinx.conf 配置文件的路径。。很不方便。。
所以我干脆 ln -s 一个在 ./ 。这样不用每次都去敲入 --config
